This flow is turtorial of 'Catch Failure Block'
- You should call 'Catch Failure Block' before error occur
- defult retry limit is 3
- If you not connect other block with 'fail dot', the fiber will occur error and be stopped
- Can catch failure!
- Debug easier~!
- Don't have to check other flow is running when you want to start the flow.
- Your flow will not easily stop because of error
- Change retry limit to 3
- turn off logging
- the log of number is for showing how the flow goes
